I'm sure I'm going to regret this, but the link below has portraits of myself to demonstrate focus and sharpness of the D800. First, I need a haircut and a shave, and I look like crap, so please don't bash me! I'm not sure, I may take down this gallery soon! But here's how I conducted the test -
First four shots are at f1.4, ISO 100, 1/60, handheld, AFS. First shot = center-left focus point, Second Shot = center focus point, Third Shot = center-right focus point, Fourth Shot = upper-right focus point.
Last four shots are at f5.6, ISO 100, 1/60, handheld, AFS. First shot = center-left focus point, Second Shot = center focus point, Third Shot = center-right focus point, Fourth Shot = upper-right focus point.
1/60 handheld in studio environment is no problem wide open, or at 5.6 for that matter. Each focus point is extremely accurate. I forgot to set the kelvin manually, so you'll notice a warmer WB on the 5.6 shots. But still very decent for AWB. I'm extremely satisfied with the 85 1.4g and i'm impressed with the sharpness and image quality of the D800. The accuracy of the AF system with all of the available AF points is impressive.
I think I've answered most of the concerns expressed on forums, such as DPReview, regarding hand-holding, focus, sharpness, shooting wide open, etc.
EDIT: taking the gallery down later today, just wanted to demonstrate the accuracy of the focus, much prettier people coming soon!
